Dell Inspiron 7791 2-in-1 — Features, Specs, Performance & Business Use

The Dell Inspiron 7791 2-in-1 is a large-format convertible aimed at professionals who want the flexibility of a tablet with the productivity of a 17.3-inch laptop. Launched as part of Dell’s Inspiron 7000 series, the 7791 combines a roomy Full-HD touchscreen, 10th-generation Intel U-series CPUs, optional discrete NVIDIA MX graphics and a robust hinge that rotates the display into tablet, tent or stand modes. It’s a compelling choice for teams that value screen real-estate for spreadsheets, multipage documents and creative review, but still need a convertible for presentations and touch/pen input. 

Below you’ll find a deep, practical look at features, technical specs, real-world performance, business use cases, deployment tips and the strengths & limitations to consider when evaluating the 7791 for a fleet.

What the Inspiron 7791 is trying to solve

The 17.3-inch convertible addresses two common business needs at once: (1) a large, readable display for complex work (Excel models, long documents, CAD proofs, multipane dashboards) and (2) tablet-style interaction for demos, markups and touch-based collaboration. Instead of carrying both a laptop and a separate tablet, the 7791 aims to be one device that can switch roles — a plus for sales, creative review sessions and mobile presentations. Dell also equipped it with “adaptive thermals” to keep performance sensible in a thin convertible chassis.

Key features & highlights

• Large 17.3″ Full HD touchscreen (1920×1080) with narrow bezels — more vertical and horizontal workspace than typical 13–15″ laptops for simultaneous windows and detailed spreadsheets. 

• Convertible hinge that rotates 360° so the device works as laptop, tent, stand or tablet — useful for presentations, shared review and annotation.

• 10th-Gen Intel Core U-series processors (i5/i7 options such as the i7-10510U) delivering good single-thread and burst multi-core performance for office workloads. 

• Optional NVIDIA GeForce MX250 discrete GPU on many SKUs (lower-power mobile GPU), giving a boost for GPU-accelerated photo/video tasks and smoother graphical previews. 

• Flexible storage & memory — PCIe NVMe SSD options (256–1,000 GB) plus configurations with Intel Optane in some retailer SKUs; RAM commonly configurable up to 16–32 GB depending on region.

• Adaptive thermals & full keyboard with numeric keypad — an emphasis on usability for long typing sessions (finance, admin) while managing heat in a large convertible chassis. 

These features position the 7791 between thin ultrabooks and heavier 15–17″ desktop replacements — it tries to give the best of both worlds for users who truly benefit from a large screen.

Practical specifications (the ones that matter)

Below are the load-bearing specs you’ll reference when comparing SKUs. (Dell shipped multiple regional configurations; verify the precise SKU spec before procurement.)

• Display: 17.3″ FHD (1920×1080) WVA touchscreen, typical luminance ~270 cd/m². 

• CPU: 10th-Gen Intel Core i5 / Core i7 (U-series; e.g., i7-10510U). 

• GPU: Intel UHD integrated or NVIDIA GeForce MX250 (25 W mobile variant on many SKUs). 

• Memory: Typically 8–16 GB factory, user-upgradeable on many configurations; some listings show up to 64 GB support (verify region). 

• Storage: M.2 PCIe NVMe SSD (configs up to 1 TB), some SKUs combine SSD + HDD or include Optane caching. 

• Battery: 4-cell 68 Wh typical (real runtime depends on panel, CPU and discrete GPU use).

• Ports: USB-C with Thunderbolt/DisplayPort (depending on SKU), USB-A ports, HDMI, SD/microSD reader, headset jack; microSD on some configurations.

• Dimensions & weight: About 397.9 × 271.1 × 15.9–20.6 mm; weight varies with configuration up to ~2.78 kg (6.12 lb) — heavier than a typical 13–15″ laptop but expected for a 17″ convertible. 

(Those figures give you the practical footprint and expandability considerations for deployment.)

Real-world performance — what to expect

Office productivity & multitasking. For standard knowledge-work (Office, email, web apps, video calls) the 7791 performs very well: Core i5/i7 U-series CPUs provide snappy single-thread performance and good responsiveness when paired with NVMe storage and 8–16 GB RAM. The larger screen reduces context-switching and improves productivity when working with big spreadsheets or multiple documents.

Media, light creative & GPU-assisted tasks. Configurations with the MX250 provide a meaningful uplift for GPU-accelerated tasks: Lightroom exports, Premiere’s GPU encodes, basic 3D previews and smoother UI acceleration when manipulating large images. It’s not a workstation GPU, but for marketing teams and content creators who edit short videos or do heavy image manipulation occasionally, the MX-equipped SKU is a sensible compromise. 

Thermals & acoustic profile. Dell’s “adaptive thermals” and a larger chassis help keep throttling in check better than smaller convertibles, but under extended full-tilt CPU+GPU loads you’ll still hear fans and see thermal limitations compared to thicker 17″ workstations. For day-to-day office bursts and meeting-room presentations you’ll rarely hit those limits. 

Battery life & mobility tradeoffs. The 68 Wh battery is respectable for a 17″ convertible, but real battery life depends heavily on screen brightness, discrete GPU use and workload. Expect a full workday only under light to moderate use; heavy editing or video calls will require charging during the day. The device’s weight makes it less suited for frequent airline travel where ultralight is required. 

Business use cases — who benefits most

1. Finance & analysts: Large spreadsheets, multi-window dashboards and a numeric keypad make the 17.3″ form factor ideal for financial modelling and reporting.

2. Marketing & content teams: A MX250 SKU lets teams proof images and edit short clips in-house without sending material to an external workstation.

3. Sales & client demos: Convertible modes (tent/stand/tablet) make the device useful for client presentations, on-site demos and collaborative markups.

4. Education & classrooms: The large screen and convertible flexibility suit instructors who annotate content, present to groups and want touch/pen input.

5. Remote workers who favour screen space: Home workers who need a “desktop-like” canvas but occasional tablet mode benefit from the 7791’s hybrid nature.

Deployment & IT recommendations

• SKU mapping by role: Choose Core i5 + 8–16 GB + SSD for standard knowledge workers; i7 + 16–32 GB + MX250 for content creators and power users.

• Docking & peripherals: If staff use the 7791 at a desk, standardize on a Thunderbolt/USB-C dock that supplies power, Ethernet and external display(s). Confirm your SKU supports TB3/PD. 

• Imaging & drivers: Use Dell’s support pages for the exact 7791 SKU to build your corporate image — the manual and driver bundles are SKU-specific and published on Dell’s site. 

• Security & manageability: Enable BitLocker, use TPM, and test webcam/audio performance with your conferencing stack (Teams/Zoom) — convertible hinge and camera position differ from standard laptops and can affect meeting ergonomics.

Strengths & limitations — quick checklist

Strengths

• Big 17.3″ touchscreen provides unmatched workspace in a convertible.

• Flexible convertible modes for presentations and touch/pen workflows.

• Optional discrete MX GPU helps creative teams without forcing a heavy workstation. 

Limitations

• Heavier than typical ultraportables — less ideal for frequent air travel.

• Battery life is workload-dependent; heavy GPU/brightness use shortens runtime.

• Not a replacement for high-end mobile workstations when prolonged sustained compute is required. 

Final verdict

The Dell Inspiron 7791 2-in-1 is a smart niche device: it gives the productivity advantages of a large 17.3-inch canvas while retaining the convertible flexibility that supports client demos, on-screen annotation and tablet-style review. For small teams that need more screen real-estate — finance, marketing, education and sales — the 7791 is a compelling one-device solution. Select the MX250 SKU for occasional creative workloads; pick more RAM and NVMe storage to keep multi-app performance snappy. If your priority is absolute portability or sustained workstation-class compute, look elsewhere — but if screen space plus convertible versatility are mission-critical, the 7791 hits the sweet spot.
